Monitoring Pacific walrus coastal haulouts by satellite to estimate herd abundance and distribution

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We monitored Pacific walrus haulouts with drone and satellite imagery to derive new methods for estimating minimum population size. The largest herd observed during an 8‐year study period was on the coast of northeastern Russia at Cape Serdtse‐Kamen in autumn 2022 where the aggregation spanned over an area of 184,094 m2 with a mean density (and 90 ...

The essential role of large research vessels in marine ecosystem observations and ocean sustainability

Limnology and Oceanography, Volume 70, Issue 9, Page 2767-2792, September 2025.
Abstract Our understanding of marine ecosystems and ability to manage them sustainably has come from multidisciplinary observations made repeatedly over long periods of time. These long‐term ecosystem observations depend on the capabilities of large research vessels, which play an essential role in the collection of global ocean observations.

AI sea ice forecasts for Arctic conservation: A case study predicting the timing of caribou sea ice migrations

Ecological Solutions and Evidence, Volume 6, Issue 2, April–June 2025.
This case study explores how new AI‐driven sea ice forecasts can support Arctic wildlife conservation. Focusing on the waterways south of Victoria Island (Nunavut, Canada), we show that predicting freeze‐up dates could help anticipate Dolphin and Union caribou sea ice crossing times weeks in advance.
